Getting tired of the S60 calculator? We were, so we made our own. Using some of the concepts that make ControlFreak so easy to use, we removed the need to select on-screen buttons and moved all the operations to the joystick. Doing basic calculations on your phone is now only a couple of clicks away.

So how fast is it?

Try this simple example: start the standard calculator and do 2/3 x 7. It takes 13 clicks. Using Calcium it only takes 6!

Best of all, it's free

Calcium is completely free and works with all 1st, 2nd and 3rd edition S60 phones (refer to the official list of S60 phones).

S60 3rd Edition updated to version 1.20:

No more customised versions. Works on all resolutions and includes RPN mode

Indicator for when there is a value in memory and memory is not lost when restarting the application
